ABSTRACT
Background: Data
on the clinical profile of breast
cancer from Jordan is scant, due to
different factors such as lack of
proper statistical centers, different
lifestyle, and different socio-demographic
structures.
Aim: To analyze the clinical
presentation and outcome of Jordanian
patients with breast cancer.
Materials and methods: Data
from 184 patients registered and treated
at different Royal Medical Services
Hospitals in Jordan from January 2002
to December 2005 were analyzed. The
analysis concentrates on age, site,
lymph nodes status, grade and type
of the breast cancer found in Jordanian
patients.
Results: The median age was
52.5 years and 54% of patients were
pre-menopausal. Ninety-six per cent
(177) patients presented with a lump.
Stages 1 (14/184), Stage 2 (111/184),
and Stage 3 comprised (59/184). Right
breast involved in breast cancer was
(93 /184), left breast involvement
(90/184) and one case had a bilateral
involvement. Most patients who needed
chemotherapy were prescribed Tamoxifen
for 5 years. The majority (86.4%)
had a lump size > two cm.
Conclusions:
- The study's results indicated
that breast cancer prognosis in
Jordan remains poor, primarily due
to late diagnosis.
- Since breast conservation protocols
yield results similar to mastectomy,
its use should be extended. Search
for biological prognostic indicators
should continue for their potential
use as guides for treatment decisions.
- Tumor size, grade and year of
diagnosis all have significant constant
effects on disease-specific survival
in breast cancer, while the effects
of age at diagnosis and disease
stage have significant effects that
vary over time.
- The histologic type is important
to consider in the prognosis and
treatment of women diagnosed with
breast cancer.
- Future studies of survival of
node-negative patients should include
information on co-morbidity and
treatment.

Breast
cancer is the most common cancer and the
second leading cause of cancer death among
women in general; annual breast cancer deaths
are exceeded only by those for lung cancer.
(1)
The traditional diagnostic approach to breast
lumps include physical examination, ultrasound
and a mammogram screening procedure. These
diagnostic procedures have a relatively
low sensitivity regarding definite malignant
small breast lumps and have largely been
replaced by cytological lump evaluation.
Breast cancer is one of the most common
malignancies in women and the incidence
has been increasing. Cytology play an important
role not only in the diagnosis of breast
lesions, but also in keeping the benign
-to -malignant biopsy ratio low, so that
unnecessary surgery is not performed. However,
breast carcinomas do not always show every
feature of malignancy. The well- differentiated
or low-grade carcinomas are often difficult
to differentiate from benign cells .It may
be helpful to consider the clinical and
radiological findings.
Conservative treatment
of multifocal breast cancers, which can
be completely removed by a single lumpectomy,
seems, when technically feasible, an alternative
to mastectomy. The increasing prevalence
of breast cancer in our society has produced
an ever-greater demand for new diagnostic
and therapeutic technologies. Today, patients
ask not only that these new technologies
offer improved diagnostic and treatment
capabilities but also that the procedures
are convenient, cost-effective, and less
invasive than before. Other diagnostic tools,
such as sonography, mammography, magnetic
resonance imaging and scintimammography,
are now available .The additional information
afforded by these technologies is intended
to limit the number of patients who need
further evaluation with breast biopsy. Early-onset
breast cancer may differ with respect to
etiology, clinical features and outcome
compared with breast cancer in older women.
Clinically most of the patients with malignant
breast lump had a palpable mass, which signifies
the role of routine self-examination and
screening programs.
Late diagnosis is a
major factor for increased mortality as
the majority of the patients present in
advanced or metastatic stage. This is primarily
attributed to lack of access to medical
facilities, virtually non-existent breast
cancer screening programs, lack of awareness
and social-cultural attitudes. . A recent
meta-analysis of the breast cancer screening
trials indicates that screening reduces
the mortality rate by approximately 25%
(2).
Data
from 184 patients registered and treated
at different Royal Medical Services Hospitals
in Jordan from 2002 through 2005 were analyzed.
The analysis concentrated on age, site,
lymph nodes status, grade and type of the
breast cancer, found in Jordanian patients.
Case records of all
the female patients presented at the surgical
Clinic in the Royal Medical Services Hospitals
over a four-year period from January 2002
to December 2005, were retrieved. EBC (Early
Breast Cancer) was defined as tumors of
less than five centimeters (T1, T2), with
either impalpable (N0) or palpable (N1)
but not fixed lymph nodes, with no evidence
of distant metastases (M0), corresponding
to Stages I. Patients with tumors more than
five cm (T3) were included if they had N0
M0 disease; Stage IIb. All EBC cases with
pathological confirmation either by fine
needle aspiration cytology or core biopsy
and who had been treated by at least one
mode of treatment (surgery, chemotherapy
or radiotherapy) were included in the analysis.(Table
1.). Data from 184 patients was thus
analyzed. All patients were followed up
every three months after discharge from
the hospital, following the initial treatment.
The
median age was 52.5 years and 54% of patients
were pre-menopausal. 5% have unknown menopausal
status and 41% had a post menopausal status.
Ninety-six per cent (177) patients presented
with a lump. Stages 1 (14/184), Stage 2
(111/184), and Stage 3 comprised (59/184).
Right breast involved in breast cancer was
(93 /184), left breast involvement (90/184)
and one case had a bilateral involvement.
Most patients who needed chemotherapy were
prescribed Tamoxifen for 5 years.

Median
ages at menarche and menopause were 14 years
(range 12-17 years) and 46 years (36-56
years), respectively. 177 (96%) patients
presented with breast lump. The majority
(86.4%) had a lump size > two cm. 77
(15.8%) had pain and 24 (4.9%) additionally
had nipple discharge.
All patients underwent
surgery; either a breast-conserving surgery
(BCS) was carried out or simple mastectomy
with axillary clearance was performed. Invasive
ductal carcinoma was the commonest histology
in 151 (82.1%) patients followed by invasive
lobular carcinoma in 18 (9.7%), mixed type
12(6.5%) and medullary carcinoma in three
(1.6%).
Adjuvant radiotherapy
was given to some patients; indications
included T3 tumor size, = 4 positive axillary
nodes, (Table 2), positive
margins, and BCS. Chemotherapy was administered
to other women. Most of the patients were
given CMF regimen at the oncology clinic.
Breast
cancer is a major cause of cancer deaths
in women and is increasing in incidence.
There appears to be a leveling off in the
incidence of breast cancer; previously the
incidence had been increasing. A typical
pathology report should indicate the type
of breast cancer, the histologic grade,
the size, and a comment on the surgical
margins. In addition, depending upon the
case, ancillary studies examining for estrogen
and progesterone receptors may be ordered.
The age-specific incidence rate curve for
breast carcinoma overall increases rapidly
until age of about 52 years, and then continues
to increase at a slower rate for older women.
Breast cancer clinical
research
An important goal is to analyze how factors
are seen to affect the disease process.
Meanwhile, the disease progression is not
fully modeled using standard analysis since
transitions between intermediate events
such as local-regional recurrences or metachronous
contra lateral breast cancer are not considered.
In the present study
Breast cancer was usually self-diagnosed
and tumors were > 2 cm at presentation
in some of the cases, suggesting the possibilities
of a delay in diagnosis, more aggressive
tumors or both. Menopause did not seem to
have any effect on Breast carcinoma as evidenced
by steadily rising rates at all ages.
The 3 known causes of
human breast cancer, ionizing radiation,
exogenous ovarian hormones and beverage
alcohol, offer some preventive possibilities
but do little to explain the epidemiologic
features of the majority of cases of the
disease that occur in their absence (3)
There is no evidence
that detection bias plays a major role,
and although the right breast is slightly
larger, on average, than the left, there
is little evidence that breast size is associated
with breast cancer risk. The reason for
the right-sided excess among women in our
study remains unclear.
Breast carcinoma is
an unpredictable disease in the sense that
some patients may present with relatively
early disease and die of widespread metastases
within six months to one year, while others
present with fairly advanced disease and
yet survive longer (4). The various histologic
types of breast cancer exhibit differences
in regard to relative frequency, site pattern
within the breast, and patient survival.
Young patients with
breast cancer had the worst histopathological
features and the worst survival rate compared
to their older counterparts. Age was an
independent significant prognostic factor
for relapse. (5). Tumor size, grade, race
of patient, and year of diagnosis all have
significant constant effects on disease-specific
survival in breast cancer, while the effects
of age at diagnosis and disease stage have
significant effects that vary over time.
(6)
Younger patients as
a group have more aggressive and advanced
breast cancer at presentation compared with
older patients. Considered in a multivariate
model, together with other variables, age
does not provide independent prognostic
information and should not be used alone
for management decisions (7). Young breast
cancer patients have poorer outcomes, which
are in part attributed to later stage disease,
more aggressive tumors, and less favorable
receptor status. There still appears to
be other important factors that are contributing
to the worse outcomes for these young patients,
such as socio-economic status. Physicians
need to have heightened awareness when evaluating
this population, and increasingly efficacious
adjuvant therapies need to be developed.
-The outcome of these patients may be improved
by patient education and availability of
better health care facilities
-Axillary ultrasonography
is increasingly being used to improve the
staging of breast cancer patients who have
negative axillary lymph nodes on physical
examination. (8) This approach has a number
of advantages. First, node-positive patients
identified with ultrasonography can be referred
for axillary dissection, without the need
for sentinel lymph node (SLN) staging. (9)
The probability of death from breast cancer
exceeded that from all other causes for
patients diagnosed with localized disease
before age 50 years, with regional disease
before age 60 years, and with distant disease
at any age. (10) There is little evidence
that breast size is associated with breast
cancer risk. (11)
Patient care decisions occur in the context
of breast cancer and other age-related conditions.
Co-morbidity in older patients may limit
the ability to obtain prognostic information
(i.e., axillary lymph node dissection),
tends to minimize treatment options (e.g.,
breast-conserving therapy), and increases
the risk of death from causes other than
breast cancer. (12). In general breast cancer
is a major public health problem in Jordan.
Late presentation is a major concern, as
large numbers of early breast cancer patients
are still diagnosed in clinical Stage II.
Patient preference for mastectomy is an
important reason for the under-utilization
of breast conservation therapy. Education/awareness
campaigns, improvement of socio-economic
conditions, better access to diagnostic
resources, availability of higher standards
of health care, use of breast self-examination,
and screening mammography if implemented
nationally would go a long way towards increasing
early diagnosis and improved survival with
a consequent possible rise in incidence
of early cases as is happening in the West.
In
our study there was no impact on recurrence
of breast cancer with regard to size, age,
menopausal status, nodal status, histologic
subtype, adjuvant therapy, or extent of
surgery.
- The study's results
indicated that breast cancer prognosis
in Jordan remains poor primarily due to
late diagnosis.
- Since breast conservation
protocols yield results similar to mastectomy,
its use should be extended. Search for
biological prognostic indicators should
continue for their potential use as guides
for treatment decisions.
- Mammogram is a valuable
tool in early detection of breast cancer;
this is especially in bilateral breast
cancer, which is invariably advanced when
diagnosed.
- Tumor size, grade
and year of diagnosis all have significant
constant effects on disease-specific survival
in breast cancer, while the effects of
age at diagnosis and disease stage have
significant effects that vary over time.
- Future studies of
survival of node-negative patients should
include information on co morbidity and
treatment.
- We conclude that histologic
type is important to consider in the prognosis
and treatment of women diagnosed with
breast cancer.
